  RulingsFinal written decision

  • BurdenNot shown unpatentable

    “A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A. Thus, for these additional reasons, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over Saxler, Beach, and Shenoy.” slip op. at 34

    “remove the recess in Saxler Figure 1A to arrive at the allegedly enhancement mode transistor of Modified Figure 1A. Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68. Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A. Pet. 25, 40, 45. For example, Petitioner asserts that Saxler’s gate contact may be “recessed or non-recessed” and that when the gate recess shown in Figure 1A is not utilized, Saxler would have the structure of Saxler Modified Figure 1A. Pet. 25 (citing Ex. 1003 ¶ 81; Ex. 1007 ¶ 52, 66); see also Pet. 40, 45 (citing Ex. 1007 ¶ 52). Neither of these paragraphs provide sufficient motivation to a POSITA to remove the gate recess from Saxler Figure 1A. Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein. Ex. 1007 ¶ 52. Petitioner’s expert, Dr. Shealy states that he understands paragraph 52 to mean that it is “fair game to pull the recess out of any of those figures [Figures 1A through 6].” Ex. 2004, 39:12–21.

    “We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

    “understanding of a person of ordinary skill in the art (sometimes abbreviated herein as “POSITA”). Graham, , 383 U.S. at 17–18. Petitioner argued that a person of ordinary skill in the art would have had a “at least a four-year degree in electrical engineering, chemical engineering, physics, or material science or a closely related field and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies. Additional education could substitute for professional experience and vice versa.” Pet. 11 (citing Ex 1003 ¶ 69). Patent Owner did not dispute this proposed definition prior to institution. See generally Prelim. Resp. In our Decision on Institution, we adopted Petitioner’s proposal. After institution, Patent Owner asserted a slightly different definition of a POSITA, namely someone who “would have possessed at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” Resp. 17. Relevant graduate education could substitute for the professional work experience. Id.

    “We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

    “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

Neither the Petition nor Mr. Andrews’s Declaration, however, provide any sufficient basis to find that even a portion of the header or header information is copied from the received message to the response message. Mr. Andrews states his opinion as though it were fact without providing the underlying factual support for his opinion. See Ex. 1003 ¶¶ 102, 118; see 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). In cross-examination, Mr. Andrews provided additional information explaining which portion of the headers he believes are the same, but he still does not provide any explanation as to why he believes the information is copied. See, e.g., Ex. 2007 at 111:3–25. The same is true of Petitioner’s Reply, which reiterates Mr. Andrews’s deposition testimony, but still fails to provide any reason as to why Coffee’s charts or Mr. Andrews’ testimony necessarily means that Coffee copies a portion of the header from the received message to the response message. See Continental Can Co. U.S.A., Inc. v. Monsanto Co., 948 F.2d 1264, 1269 (Fed. Cir. 1991) (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”). And, despite Petitioner’s identification of a “Header” listed in Tables 58 and 63, Coffee does not expressly describe the header or part of the header as being copied from the received message to the response message. The Petition and Mr. Andrews also state that “if Coffee did not employ such copying, the response message would not automatically include information extracted from the received message.” Pet. 38 (citing Ex. 1003 ¶ 118). But, Coffee does not expressly describe the header as being “extracted from the received message” or describe automatically including the header in a response message to make the leap argued by Petitioner and Mr. Andrews. Accordingly, on the full record before us, we find that Petitioner has not established that Coffee explicitly or inherently discloses copying the header or header information and we do not credit Mr. Andrews’ testimony, discussed above, because he fails to provide the underlying factual basis for the opinions offered.” slip op. at 43

Samuels, 812 F.3d 1056, 1068 (Fed. Cir. 2016))). Coffee does not explain the process by which the IOD of the received message is included in the response message; rather, Coffee just states that the response message “contains the IOD of the message being answered.” See, e.g., Ex. 1005, 56:63–67 (see full text quoted above). In particular, although Coffee attributes certain actions to the operator, the lack of attribution to the operator does not necessitate that the only viable possibility remaining is that Coffee copies the IOD from the received message to the response message. Even if it may be said that Coffee probably (or possibly) copies the IOD, that probability is not sufficient to find that Coffee necessarily copies the IOD. See Continental Can, 948 F.2d at 1269 (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”).7 Additionally, on the full record before us, we determine that Mr. Andrews’s testimony, as with his testimony as to copying of the header and selected response, fails to provide any factual or underlying support for his opinions expressed therein. See Ex. 1003 ¶¶ 100–102. In particular, the leap occurs in paragraph 102, where Mr. Andrews takes the fact that some information (at least the IOD) from the received formatted message is included with the response message to opine that this means the information is “copied over.” Id. ¶ 102. But, again, Coffee is silent. And because Mr. Andrews did not provide any underlying factual basis for his opinion, we do not credit his testimony as to copying the IOD. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 48

    “generally, including the alleged benefits of such and reasons why one of ordinary skill in the art would have been prompted to include field-mapping information in Coffee’s MDT. See id. at 62–70. None of Petitioner’s discussion, however, explains how the combination of Coffee and Heijden remedies the deficiencies that we identified regarding Petitioner’s challenge based on Coffee. In particular, Petitioner does not assert or explain how the teachings of Heijden would be applied to Coffee such that Coffee would then copy or fill in the specific information from Coffee’s received message to Coffee’s response message, particularly as pertains to the header, Response, and IOD fields (which Petitioner relied on in the first ground), or any other information field from Coffee. The same is true of Mr. Andrews’s testimony. See Ex. 1003 ¶¶ 214–231. Additionally, it appears that Petitioner’s analysis of the combination of Heijden and Coffee maintains the position that Coffee copies information fields. See Pet. 70 (“Given that Coffee’s system already implements field mapping to copy information fields . . . .”). And, Mr. Andrews’s testimony similarly maintains that Coffee copies information fields. See Ex. 1003 ¶ 229 (“Coffee also discloses (at least inherently) field mapping by describing that data is copied from fields in request messages into corresponding fields in response message.”). But, as we explain in detail in the context of Petitioner’s challenge based on Coffee, Petitioner has not shown sufficiently that Coffee copies or fills in information from a received message to a response message. Thus, we do not find and Petitioner does not allege that Ground “1B” fills the gaps identified in Petitioner’s Ground “1A.”10 Accordingly, we determine that Petitioner has not established, by a preponderance of the evidence, that the combination of Coffee and Heijden would have rendered the subject matter of claims 1–4, 7–9, and 12 unpatentable.” slip op. at 60

    “Neither party contends that the differences in proposals affect the outcome of this proceeding and we do not find that they do. Nonetheless, on the full record before us, we find that our identification of the level of ordinary skill in art from the Institution Decision as well as Patent Owner’s option (b) are supported by the prior art of record, the ’474 patent, and the opinions of Drs. Subramanian and Steer (which, as discussed above, recognize that additional work experience can compensate for the lack of a formal degree). Accordingly, we modify our preliminary finding to include the specifics from option (b) of Patent Owner’s proposal. Thus, we find that one of ordinary skill in the art would have at least a bachelor’s degree in electrical engineering or a related subject and two or more years of experience in the field of RF circuit design, or at least five years of work experience and training in the design and development of RF circuits and/or systems.

In its Reply, although Petitioner disagrees with Patent Owner’s interpretation of the claims as limited to energy sampling (i.e., energy transfer systems) (Pet.

    “the case law makes clear that “an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising’” unless an “extremely limited” exception applies. See Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016) (quoting KCJ Corp., 223 F.3d at 1356; Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342 (Fed. Cir. 2008)). Here, claim 1 recites the transitional phrase “comprising,” meaning it is open-ended, and, therefore, the usual meaning of “a” as “one or more” would have been expected absent an extremely limited exception. In considering whether an exception applies, our review of the ’720 patent fails to indicate that the patentee intended the phrase to mean anything other than the usual meaning of “one or more.” Patent Owner asserts that “‘[t]he plain language of the claim clearly indicates only a single [list] is used’ to list multiple assets” and quotes two portions of the Specification, which state “a list of assets that satisfies criteria” and “a list of assets to which a . . . device is granted access.” PO Sur-reply 15 (quoting Ex. 1001, 12:60–67) (citing Ex. 1001, 2:23–34, 3:1–5, 4:21–23, 17:59–66). Although claim 1 of the ’720 patent recites “assets” in the plural, we fail to see how that conveys that the term “a” would have been understood as limited to “one.” Notably, neither party has identified any inconsistency, in the claims or other portions of the Specification (including the portions quoted and/or cited by Patent Owner), resulting from construing “a” as “one or more.” And, we find that there is no reason why the claims could not be met under the construction of “a” as “one or more.” Thus, we find that the ’720 patent does not “evince [ ] a clear intent to limit a or an to one.” See Convolve, 812 F.3d at 1321 (internal quotations omitted). Accordingly, we construe the term “a” in “a list of assets” as “one or more” such that the phrase “a list of assets” means “one or more list of assets.” Considering next the phrase “the list of assets” recited in limitation 1[d], the parties do not dispute that the use of the term “the” means that “the list of assets” refers back to the one or more list of assets retrieved in limitation 1[c] and discussed above. See PO Resp. 3–4; see generally Pet. Reply; PO Sur-reply 5. Similarly, the parties do not dispute that the phrase “the filtered list of assets,” recited in limitation 1[e], refers back to the list of assets resulting from the filtering step of limitation 1[d]. See PO Resp. 3–4; see generally Pet. Reply; PO Sur-reply 5. We agree with the parties that each of these phrases refers back to the previous instance of the recited terms.” slip op. at 14

    “Fundamentally, Petitioner fails to provide any reason in the Petition as to why one of ordinary skill in the art would have found it obvious to retrieve a list of assets based on Lewis. Instead of providing a reason as to why retrieving a list of assets would have been obvious, Petitioner points to a result achieved by Lewis—generating a dynamic manifest file that contains a list of URLs to container files containing content. In the context before us, pointing to a result to allege that a step in a process leading to the result would have been obvious is insufficient without also providing a reason with rational underpinning. See KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”)). Here, Petitioner relies upon the result of Lewis’s process—generating a dynamic manifest file containing a list of URLs—as the only basis as to why a previous step in the claim would have been obvious without providing any reason why the achieved result means the previous step would have been obvious. Further, although Petitioner cites to Dr. Reader’s declaration (Ex. 1003 ¶ 233), Dr. Reader’s testimony does not provide any further explanation or reason as to why this aspect of limitation 1[c] would have been obvious.11 Rather, the Petition’s 11 To the extent Petitioner relies upon its discussion of the combined teachings of Lewis and Marusi as set forth at the beginning of Petitioner’s discussion of this ground (see Pet. 54–57), that portion of the Petition does not provide an additional reason why retrieving a list of assets as recited in discussion appears to be exactly the same as Dr. Reader’s testimony on this point.

The trial practice guide elaborates on these rules, explaining that “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Consolidated Trial Practice Guide November 2019 (“CTPG”)13 at 73. “While replies . . . can help crystalize issues for decision, a reply . . . that raises a new issue or belatedly presents evidence may not be considered.

Applying the foregoing legal authority, we agree with Patent Owner that Petitioner’s Reply improperly introduces new argument and new evidence.

Krames’ TIP geometry and Rossner’s phosphors, as asserted in the Reply (Pet. Reply 7). GaN-on-SiC LEDs are not disclosed in Hochstein, Masatoshi, or any of the other references asserted in the Petition. As support for its contention that GaN-on-SiC LEDs were known, Petitioner relies on two new references—the ’499 patent and the Cree article—that were not cited in the Petition or the Shackle Declaration. Petitioner argues that its reply argument and evidence are not new, but were presented to “show[] that Patent Owner’s statements were false and contrary to what was known in the prior art; namely, that you can cut the substrates related to GaN-based LEDs, specifically, silicon carbide substrates, using a beveled blade.” Tr. 34:4–8. We disagree. The Petition relied on Hochstein in view of Krames or Masatoshi as teaching “a light emitting cell array . . . comprising a plurality of light emitting cells connected in series on a substrate,” as recited in claim element 1a. Pet. 36–37, 54–55. In its Response, Patent Owner argued that the LEDs disclosed in Hochstein, Masatoshi, or Krames would not work in Petitioner’s proposed combination with Rossner. PO Resp. 17.

To show that GaN-on-SiC LEDs were in the prior art, Petitioner relied on two new references: the ’499 patent and the Cree article. Exs. 1035, 1058.

See Pet. Reply 7 (arguing that Krames’ TIP geometry could have been implemented in GaN-on-SiC LEDs). Alternatively, Petitioner’s new obviousness theory requires a combination of Masatoshi’s circuit, Rossner’s storage phosphors, Krames’ TIP geometry, and GaN-on-SiC LEDs, as disclosed in the ’499 patent or the Cree article. Id. Petitioner does not, however, present a sufficient evidence-supported rationale for combining GaN-on-SiC LEDs with either Hochstein’s driving circuit or Masatoshi’s circuit. No such rationale is presented in the Petition or the Shackle Declaration, which do not mention GaN-on-SiC LEDs. Although Petitioner’s Reply and the Krames Declaration discuss GaN-on- SiC LEDs, neither document explains why a POSITA would have had reason to combine them with Hochstein’s driving circuit or Masatoshi’s circuit.

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionNo construction neededGranted

    “After considering Petitioner’s arguments regarding claim 9, Patent Owner’s silence regarding claim 9, and the language in the ’070 patent itself (e.g., Ex. 1001, 11:45–52, 12:60–61), we agree with Petitioner that the term “1H, 1H, 2H, 3H-heptadecafluorodecylacylate” in claim 9 should be construed to correctly recite HDFDA (1H, 1H, 2H, 2H-heptadecafluorodecylacrylate). The error Petitioner identifies is conspicuous and undisputed, and the intrinsic record does not suggest a different interpretation. Fitbit, Inc. v. Valencell, Inc., 964 F.3d 1112, 1119–20 (Fed. Cir. 2020); Novo Industries, L.P. v. Micro Molds Corp., 350 F.3d 1348, 1357 (Fed. Cir. 2003). Additionally, after reviewing the parties’ remaining claim construction arguments and evidence, we determine that we do not need to expressly construe any other terms for purposes of this Decision because, as addressed in detail below, we find Petitioner’s showings deficient for reasons that do not depend on the construction of any claim term. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)).” slip op. at 6

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “B. Level of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art in the field of the ’070 patent would have had “at least a bachelor’s degree in a field such as chemistry, physics, or chemical engineering, as well as at least two years of experience with plasma-polymerization techniques.” Pet. 14 (citing Ex. 1002 ¶¶ 26–31). Patent Owner agrees with this proposed definition “with the understanding that ‘experience with plasma-polymerization techniques’ includes plasma-enhanced chemical vapor deposition (PECVD) techniques.” PO Resp. 9 (citing Ex. 2010 ¶ 20; Ex. 1002 ¶¶ 12, 63). In light of the record before us, we adopt Petitioner’s proposal regarding the level of one of ordinary skill in the art. As Patent Owner points out, Dr. Gleason states that PECVD is a form of plasma polymerization, and thus the parties agree that experience with plasma-polymerization techniques would include PECVD. PO Resp. 9; Ex. 1002 ¶ 63. The level of ordinary skill in the art is also reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 7

  • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Not shown unpatentableNot shown unpatentable

    “We agree with Patent Owner. Petitioner has failed to demonstrate adequately that each and every element in claim 1, arranged as recited in the claim, is found in a single prior art reference. NetMoneyIN, 545 F.3d at 1369; Karsten Mfg. Corp. v. Cleveland Golf Co., 242 F.3d 1376, 1383 (Fed. Cir. 2001). Here, Petitioner combines several different teachings from Baalmann to support its anticipation argument. For example, Petitioner relies on the “evacuable chamber with a volume of 1 m3” from Baalmann’s Example 1, but not the power (2kW) expressly disclosed as being used with that reactor of Example 1. Ex. 1004 ¶ 47. With regard to power density, Petitioner relies on Baalmann’s general disclosure that “[t]he electrical power input per chamber volume is set between 0.5 kilowatt/m3 and 5 kilowatt/m3.” Ex. 1004 ¶ 20. As Patent Owner points out, however, that power density range is not tied to any particular reactor volume or plasma zone volume. PO Resp. 19. Baalmann also fails to expressly disclose the plasma zone volume of the reactor in Example 1. See Ex. 1004 ¶¶ 47–48. To attempt to overcome this absence of an express disclosure, Petitioner argues that, for the reactor used in Example 1, the plasma zone volume and reactor volume are the same based on the configuration of the electrodes in the reactor. Pet. 24–25. Baalmann, however, does not expressly disclose the electrode configuration of the reactor in Example 1. See Ex. 1004 ¶¶ 47–48. Instead, Petitioner relies on Baalmann’s general disclosure of an embodiment wherein one electrode is formed by the chamber wall itself. Pet. 24–25; Ex. 1004 ¶¶ 35, 61. In so doing, Petitioner ignores the fact that Baalmann also states that “[t]wo opposite rod-shaped electrodes may also be used.” Ex. 1004 ¶ 35. In view of this, we disagree with Petitioner’s conclusion that a person of ordinary skill in the art “would have understood that chamber to be configured as described throughout the rest of the specification: with the chamber wall serving as one of the electrodes.” Pet. 24. Even if we were persuaded by Petitioner’s argument, the fact remains that Petitioner’s anticipation challenge is based on the combination of different features disclosed in separate portions of Baalmann. “Such picking and choosing . . . has no place in the making of a 102, anticipation rejection.” In re Arkley, 455 F.2d 586, 587–88 (CCPA 1972) (cited with approval in Sanofi-Synthelabo v. Apotex, Inc., 550 F.3d 1075, 1083 (Fed. Cir. 2008)); see also Microsoft Corp. v. Biscotti, Inc., 878 F.3d 1052, 1069 (Fed. Cir. 2017) (stating that anticipation is not proven by multiple, distinct teachings that the artisan might somehow combine to achieve the claimed invention).” slip op. at 12

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundReasonable expectation not foundNot shown unpatentable

    “For all of the foregoing reasons, we are not persuaded by Petitioner’s argument that a person of ordinary skill in the art would have inferred the volume of the plasma zone10 in Coulson is 470 cm3 based on Coulson’s disclosure of a “glow discharge reactor” having a volume of 470 cm3. Pet. 38; Reply 15–16. In view of this, we are likewise not persuaded that Coulson discloses a power density of 85.1 W/m3, because Petitioner’s 9 Dr. Gleason confirmed that she did not perform any experiments to verify her opinions regarding Coulson’s plasma zone. Ex. 2017, 80:10–18. 10 As noted above, Petitioner presented its argument in the context of its proposed construction of plasma zone. Petitioner did not present an alternative argument supported by sufficient evidence addressing the volume of Coulson’s plasma zone based on Patent Owner’s proposed construction of plasma zone. Accordingly, we agree with Patent Owner’s assertion that we do not need to expressly construe the term plasma zone to resolve this issue. Sur-reply 1. argument that Coulson discloses this power density is based on its assertion that Coulson has a plasma zone volume of 470 cm3. Pet. 38. This finding is fatal to Petitioner’s obviousness challenge of claim 1 based on the combined teachings of Baalmann and Coulson because Coulson’s purported disclosure of using a power density of 85.1 W/m3 is an essential component of Petitioner’s obviousness challenge. An obviousness determination requires finding both “that a skilled artisan would have been motivated to combine the teachings of the prior art . . . and that the skilled artisan would have had a reasonable expectation of success in doing so.” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367-68 (Fed. Cir. 2016). In attempting to establish a person of ordinary skill in the art would have had reason to combine the teachings of Baalmann and Coulson, and would have had a reasonable expectation of success in doing so, Petitioner repeatedly refers to using Coulson’s optimized reaction conditions, including power density, in Baalmann’s larger reactor. Pet. 48 (stating that a person of ordinary skill in the art “would have been motivated to maintain the same or similar reaction conditions within a larger reaction chamber that were present in Coulson’s chamber during Coulson’s reported plasma polymerization reactions, including power density and pressure, to preserve the same effective results.”), 48–49 (“That would have included motivation to maintain Coulson’s disclosed power density when scaling up to a larger reaction volume to preserve the beneficial results Coulson reported at that optimized power density.”); Reply 23 (referring to the “straightforward, compelling obviousness case set forth in the petition” that a person of ordinary skill in the art “would have expected to succeed performing Coulson’s reactions on a larger scale in view of Baalmann”); 23 (“The petition explained why a POSA would have modified Baalmann to use Coulson’s HDFDA monomer and reaction conditions to produce coatings with a reasonable expectation of success” ), 24 (stating the Petition “explained why a POSA would have expected success using known parameters from Coulson in an established large-scale apparatus”). During the oral hearing, counsel for Petitioner confirmed its obviousness positions depend on using Coulson’s power density. Tr. 20:10–21:16. Accordingly, Petitioner’s failure to demonstrate adequately that Coulson discloses or suggests a power density of 85.1 W/m3 undermines its reason to combine and reasonable expectation of success arguments. Petitioner’s argument that Baalmann discloses the claimed power” slip op. at 26
